algorithm - Fast generation of random numbers that appear random -

-

I am searching in an efficient way to generate numbers that a human will experience in random form. Actually, I think about avoiding the long sequences of 0 or 1 bit. I hope that humans want to see a bit of pattern, and a very low CPU should be able to calculate these close to one thousand per second.

There are two different concepts which I can think of doing this, but I am losing searching to find an efficient way of accomplishing them.

  1. Generate a random number with a certain number. For 32-bit random numbers, it requires 31 random numbers using the Nood Selection algorithm. Is bits a more efficient way to generate a random number with some numbers of sets? Unfortunately, 0000FFFF does not look very random.

  2. Some parts feel "part-wise" density as it looks better - but I can not come together, the obvious way of doing this - I think of going through every segment, And calculate how far it is from the ideal density, and try to increase the bit density of the next part. It seems complicated.

Hopefully there is another algorithm about which I have not thought about it. Thanks in advance for your help.

[edit] Should be clear with what I should ask -
(A) Is there an effective way to generate random numbers without the "long" run of a single bit, where " Tall "is a tunable parameter?
(B) Whatever will be less, random?

Probably what you want is what you want.

Edit light in one of the updated questions: You should see one, though I'm not sure how fast it can run. See also.

c++ - Linux and clipboard -

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
